I have a 1975 Hatteras Sports Fisher, 46 ft powered by the original 871 TI detroit engines. Does any body know the original prop diameters and pitch for this configuration? I have a problem with both engines loading up and blowing black smoke and only turning about 1800 rpm with throttles wide...

My boat has those simple site gauges where a float slides up & down a spiral bent piece of steel. So simple..... but after 30 years I can't see through the lens. Anybody know where to purchase replacements? I would like some that could drive electrical gauges as well, but still like the...

Took the boat out this weekend for a 12 hour fishing trip, tranny was full when checked the privious day. On the run home, 11 hours or so the port engine changed pitch and a drop in tranny oil drive pressure noted, pulled back to an idle and checked things out and it was low on oil, refilled and...

OK major problem is fixed but now I need to fine tune. The boat is 1979 Hatteras Sportsfisher, twin 871TI detroits, with a full load of fuel, fairly clean bottom and freshly scrapped props, @ 1800 rpms gps indicates 15-16 knots @ 2100 WOT speed indicated is about 20 knots..no smoke..... does...

Several weeks ago, a number of forum members suggested that I look at the emergency air shutdown system as a potential problem for insufficient air flow resulting in black smoke and rpms limited to about 1500. I spent the day removing the air horns and as usual the advice on this forum is...

Do all 8v71ti engines have these? I have not found them on my engines? Are they between turbos and intercooler/ intercooler and blower?...? "Concerning the air-box doos for the emergency shutdown: I don't see many Detroits anymore,but I can distinctly remember a guy in Montauk that...

Some of you may remember some of my post on reworking a 46 ft Hatteras sportfisher. We'll she's in the water and we have started running her some and have found that the engines need some work. The main problem is they will not turn up to higher rpm. Based on my research on this site WOT...

I have just installed a windlass and am concerned about the length from it to the roller. There is room for the roller to project further out, it is held by a stainless steel arm. I mounted the windlass as far back as possible in the pupit because the pulpit is about five inches higher than the...

I have a 46 ft 1975 Hatteras Sport fisher with Bennett trim tabs. The units don't work and I am considering fixing them. How important are they for this boat with a cruise of about 18 knots? Would it make sense to just lock them in a fixed position for best cruise performance, or do you really...

After reading the thread on Racors 6000CVC, I am conviced I need to put this systems on my 8v71TI's. The thread was great, even had a couple of pictures that showed exactly how to do it along with references as to where to purchase. Great Job to all that contributed! In all of this I need new...

I am adding an additional control consol and have purchased new Stuart Warner electric marine gauges. I was hoping that I could use one sender unit to supply both gauges ( one on the bridge and one in the salon). I tested them and I get an incorrect reading. Is there someway to add a resistor or...

I don't know what the correct name is for the fuzzy window seals in my 1975 SF, but I know they are difficult to get out. I hate the thought of trying install the new ones......surely there is an easy way! Has anybody got a easy solutuion?

On my 1975 46ft SF, I am going to replace the old 8ds with the golf cart batteries as I have read about in the site and want to make sure I have a good charging system. I know that the old charger works well but I believe it to be of the older type that typically over charges and boils off the...

I don't have much experience with diesels so I need some help. Is the following something to be expected? I have a pare of 8V71 TI's that seem difficult to start in cooler weather 40-50 degrees farenheight. When you first turn them over you get white smoke and no start. After a period trying...

I am restoring a 1975 46ft SF HAT and have been cleaning out the bilges and have a couple of questions. How can you control oil that leaks from the engines? Currently it will move pretty much the length of the boat between the stringers. I would add that it does not flow to the center...

I have a 46ft 1975 SF, It is set up for a davit/crane that extends through the deck all the way down through the main statesroom's closet to the floor. What type of davit/crane should I be looking for and where is my best bet on finding one? As for a tender, I would like to use a small Boston...

I have enjoyed reading all the post and exchanges of information to the point that I feel I need to contribute something. So I thought I would post updates on my project. I would appreiate any advise or comments on my questions as well as my technique. I must add that I am doing this whole...

#1 I have removed all of the interior siding and noticed that there are 6" flexible ducts connected to the air vents along the side of the boat and the tops of the vents are open. Why is the top of the vent open when the duct is hooked into it? It appears to me that these vents should be covered...

While working on my boat I found some copper screen (1/4" mesh) behind my breaker panel. It practically fell apart due to corrosion. What purpose does it serve? I figure it is part of the bonding system but I am not sure. I would appreciate any information concerning this.

I am restoring a 46 ft SF and wonder why they did not use any insulation. It seems to me there would be several advantages: Easier to heat/cool, sound deadening and reducing condensation. This past winter while working on the boat I noticed the heated moist air in the boat would condensate on...
